A METAR tells you what's happening now. A TAF tells you what's coming. Paste a raw TAF and we'll break down the valid period and every FM / BECMG / TEMPO / PROB change into plain English — plus what each window means for a Part 107 flight.
FM = a clean change from that time. BECMG = gradual change over a window. TEMPO = brief fluctuations. PROB30/40 = a 30–40% chance of those conditions. Times are in Zulu (UTC), day-of-month first.Use the METAR Decoder for current conditions and this TAF Decoder to plan a flight window. The test asks about both — and both matter for a real go/no-go.
Weather minimums, METAR/TAF reading, stability, and thunderstorm logic — drilled with hundreds of explained questions. One-time $39.99.
